We had three of these installed in our new house and even after a year, are still disappointed. Comfort Height is not the same as the Kohler toilets we had in the house we built in 1992. I have 2 knee replacements and getting on/off is difficult. Otherwise, nice toilet as far as cleaning the inside. Installed only inches from the wall so haven't found a good way to clean behind them. The quiet flush is nice too.
